<p>祝贺你找到了这个页面！以下是针对这些错误消息的解释，以及这些错误出现时您可以采取的行动。</p>
<div class="section" id="where-do-these-errors-come-from">
<h2>这些错误从何而来？<a class="headerlink" href="#where-do-these-errors-come-from" title="永久链接至标题">¶</a></h2>
<p>此错误是由 TVM 执行期间违背内部规则造成的。在技术层面上，消息由 <code class="docutils literal notranslate"><span class="pre">ICHECK</span></code>  宏生成，该宏位于 <code class="docutils literal notranslate"><span class="pre">include/tvm/runtime/logging.h</span></code> 中。在执行过程中TVM 的许多地方都使用 <code class="docutils literal notranslate"><span class="pre">ICHECK</span></code> 宏来断言若干条件为逻辑真：每当断言失败时，TVM 都会退出并显示上面的错误消息。</p>
<p>有关 TVM 是如何处理并生成错误的详细信息，请参阅 <cite>错误处理指南</cite> 。</p>

<div class="section" id="what-should-i-do-when-i-encounter-such-an-error">
<h2>遇到这样的错误，我该怎么办？<a class="headerlink" href="#what-should-i-do-when-i-encounter-such-an-error" title="永久链接至标题">¶</a></h2>
<p>首先，<em>不必惊慌</em>，因为这并不能解决任何问题。</p>
<p>最好的办法是搜索 <a class="reference external" href="https://discuss.tvm.apache.org/">Apache TVM 论坛</a> 来了解您遇到的错误是否其他人也遇到过，以及可能存在的解决方案。如果此错误是由于最近某个 TVM 版本中已修复的 bug 导致的，那么您可能需要更新到更新的版本。</p>
<p>如果您在论坛中没有找到有关问题的讨论，欢迎您在论坛上开始一个新的话题，并在其中详细介绍遇到的问题。<em>请</em> 在您的帖子中包括以下关键信息：</p>
<ul class="simple">
<li><p>您正在使用的 TVM 版本（例如，代码树中对应的 git commit 哈希值）。</p></li>
<li><p>您正在使用的硬件环境以及操作系统版本。</p></li>
<li><p>TVM编译的目标硬件设备和操作系统是什么。</p></li>
<li><p>有关模型、输入或其他有关工作负载的详细信息，这些信息可用于复现您的问题。</p></li>
</ul>
<p>如果没有这些细节，TVM 开发人员很难为您提供很大的帮助。</p>
